I'd like to have a calendar combo drop down on my ribbon toolbar.

The only way I can think of to do this is to put a ControlContainerTool on the toolbar and set it's control to a UltraDateTimeEditor.

 This would be fine, but the control container takes up three lines on the ribbon, and messes up the whole layout.

How can I make the controlcontainer only take one line, like a reguar tool?
